本发明所述的太阳能电池封装用层状复合PVB胶膜值得大规模推广使用。
具体实施方式
以下通过具体实施方式的描述对本发明作进一步说明，但这并非是对本发明的限制，本领域技术人员根据本发明的基本思想，可以做出各种修改或改进，但是只要不脱离本发明的基本思想，均在本发明的范围之内。
实施例1
称取PVB树脂80千克、偶联剂20千克、相容剂15千克、润滑剂3千克、抗氧化剂15千克、增塑剂30千克和绝缘助剂5千克，所述偶联剂为硅烷偶联剂KH550。所述相容剂为丙烯腈-丁二烯-苯乙烯接枝马来酸酐。所述润滑剂为液体石蜡。所述抗氧化剂为N,N-二苯基对苯胺。所述增塑剂为邻苯二甲酸甲酯。所述绝缘助剂为：
将上述物质加热至80℃，加入高速搅拌机，以1000转/分钟搅拌10分钟，然后出料到加入长径比(L/D)为40的双螺杆挤出机中，双螺杆挤出机的加工温度：一区温度170℃，二区温度为180℃，三区温度为190℃，四区温度为205℃，五区温度为215℃，六区温度为225℃，七区温度为235℃，八区温度为240℃，主机转速为350转/min；经过挤出后冷却牵条、风干切粒，即得。
实施例2
按照和实施例1相同的方式制备样品2，不同之处在于不使用绝缘助剂：
实验例
按IEC60093要求进行测试表面电阻率，结果如下：实施例1的样品的表面电阻率(Ω)为6.9×1012，实施例2的样品的表面电阻率(Ω)为2.3×107，由此可见，加入绝缘助剂后，绝缘性到显著增强，实施例1的结果与实施例2的结果进行比较，差异具有统计学意义(P<0.05)。
